# StackState/Agent IAM role: EKS

## Overview

If StackState or StackState Agent V3 are running within an AWS environment in an EKS cluster instance, an IAM role can be attached to the node-group where the pods `stackstate-api` or `stackstate-cluster-agent` are running.

* `stackstate-api` pod - the attached role can be used for authentication by StackState running in these pods.
* `stackstate-cluster-agent` pod - the attached role can be used for authentication by StackState Cluster Agent running in this pod.

{% hint style="info" %}
Note: If the AWS Data Collection Account and the Monitor Account aren't a part of the same AWS organization, it isn't possible to authenticate using the attached IAM role in this way. For details see the AWS documentation on [AWS organizations (docs.aws.amazon.com)](https://docs.aws.amazon.com/organizations/latest/userguide/orgs_introduction.html).
{% endhint %}

## Set up IAM role for StackState/StackState Agent on EKS

To set up an IAM role for StackState or StackState Agent to use, follow the instructions below.

1. If you did not do so already, [create a policy](/5.1/stackpacks/integrations/aws/aws.md#aws-policy) that allows the `AssumeRole` action for the resource `arn:aws:iam::*:role/StackStateAwsIntegrationRole`. Take note of the policy name.
2. Find the node-group that contains nodes running the relevant pod or pods and create a node group role:
   * **StackState on EKS**: `stackstate-api`.
   * **StackState Agent on EKS**: `stackstate-cluster-agent`.
3. Attach the policy from the first step to the node-group role from the previous step.

4. Configure the StackPack instance or Agent AWS check to [authenticate using the attached IAM role](/5.1/stackpacks/integrations/aws/aws.md#iam-role-on-ec2-or-eks).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://archivedocs.stackstate.com/5.1/stackpacks/integrations/aws/aws-sts-eks.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
